The first column of this table presents annual Tobit regressions of the Acquisition ratio on the Governance Index, G, measured in the previous year, SIZE, BM, and industry dummy variables. The third columnpresents annual Poisson regressions of Acquisition count on the same explanatory variables. In the second and fourth columns, we restrict the sample to firms in the Democracy (G < 5) and Dictatorship (G > 14)Portfolios, and we include as a regressor a dummy variable that equals 1 when the firm is in the Democracy Portfolio and 0 otherwise. The coefficients on SIZE, BM, and the industry dummy variables are omitted from the table. The calculation of G is described in Section II. Acquisition ratio is defined as the sum of the value of all corporate acquisitions during a calendar year scaled by the average of market value at the beginning and end of the year. Acquisition count is defined as the number of acquisitions during a calendar year. The data on acquisitions are from the SDC database. SIZE is the log of market capitalization at the end of the previous calendar year in millions of dollars, and BM is the log of the ratio of book value (the sum of book common equity and deferred taxes) in the previous fiscal year to size at the close of the previous calendar year. Industry dummy variables are created by matching the four-digit SIC codes of all firms in the CRSP Compustat merged database in December of each year to the 48 industries designated by Fama and French [1997]. The coefficients and standard errors from each annual cross-sectional regression are reported in each
row, and the time-series averages and time-series standard errors are given in the last row. Significance at the 5 percent and 1 percent levels is indicated by * and **, respectively. All coefficients and standard errors are multiplied by 100.
